...tation for Itanium-style EH, and have a relatively low support burden. resume ------------- ; Old form still works, still means control is leaving the function. resume <valty> %val ; New form overloaded for intra-frame unwinding or resuming normal execution resume <valty> %val, label %nextaction ; New form for EH personalities that produce no value resume void Now resume takes an optional label operand which is the next EH action to run. The label must point to a block starting with an EH action. The various EH action blocks impose personality-specific rules about what the targets of t...

...action. I like this because I talk a lot about "unwind edges" in the CFG, and a cleanup finishing feels like an unwind edge. I could also see 'dispatch' here. Some possible new syntax: recover from label %maycatch.int to label %endcatchbb unwind from label %cleanup.obj to label %nextaction unwind from label %cleanup.obj ; unwinds out of the function, hook it up to the unwind edge of an inlined call site For Itanium, tail merging is profitable and doable with phis, so we might want to do this instead: recover to label %endcatchbb unwind i8* %ehptr to label %nextaction unwind i...

Thx again Evan for the review. Here's a new patch for the JIT in itself. The major changes are: 1) A JITMemoryManager now has a flag saying "I require to know the size of what you want to emit" 2) DwarfJITEmitter is augmented with GetSize* functions 3) JITEmitter::startFunction checks if the JITMemoryManager requires to know the size. If so, it computes it and gives it through the

Dear all, Here's a new patch with Evan's comments (thx Evan!) and some cleanups. Now the (duplicated) exception handling code is in a new file: lib/ExecutionEngine/JIT/JITDwarfEmitter. This patch should work on linux/x86 and linux/ppc (tested). Nicolas -------------- next part -------------- An embedded and charset-unspecified text was scrubbed... Name: jit-exceptions.patch URL:

I run a check on the address line parameters to make sure the user isn''t passing my list method a :year to search for that does not exist in the database, which would create null pointer exceptions. I then splash a flash message telling the user that the year doesn''t exist in the database. Then, if the user enters another year into the command line as an argument for the

Hi everyone, Here's a patch that enables exception handling when jitting. I've copy/pasted _many_code from lib/Codegen/DwarfWriter.cpp, so we may need to factorize it, but the functionality is there and I'm very happy with it :) lli should now be able to execute the output from llvm-gcc when using exceptions (the UnwindInst instruction is not involved in this patch). Just add the

Our company is mainly made up off application developers but we have a lot of web work coming up so we are deciding which route to take at the moment. We initially identfied ASP.NET 2.0 with the ATLAS AJAX framework because of the RAD features, easy to learn etc. I had read some stuff on ROR and our Boss who is open minded allowed me to create a sample application with ROR. He was impressed

Hi - I have read the archives on R cmd and passing parameters, and I guess I am not totally clear if that solved this problem ... I would like to call an R script from the command line, and in the process pass in data sets and parameters ... right now, I manually specify the files to be read in as the data sets for the script, and then it processes, but I need to be able to automate this

When I install the new RPM for Mandrake 8.1, it fails and cannot find: libblas.so.3, libgcc_s.so.1, and libgcc_s_so.1 (GLIBC_2.0). Any help would be very much appreciated.
